After discovering that her boyfriend Garrett cheated on her, sorority sister Megan (Audrina Patridge), with the help of her sorority friends - Cassidy (Briana Evigan), Jessica (Leah Pipes), Ellie (Rumer Willis), Claire (Jamie Chung) and Chugs, Garrett's sister, pulls a prank on him; she fakes her own death while making out with him. With the help from the sisters, Garrett brings Megan to a steel mill, intent on dumping her body in the lake. After Jessica jokingly mentions they need to release the air out of her lungs so her body will not float to the top, Garrett stabs Megan through the chest with a tire iron, killing her for real. The group decides to dump Megan's body in the mine, along with the tire iron. Eight months later. The girls have grown apart and put the incident behind them, although Cassidy still feels guilty about the whole thing. During the party held after graduation, the girls all receive a picture sent to their phones: a robed arm holding the bloody lug wrench Garrett used to kill Megan. Suspicion falls on Garrett, but Chugs insists he's changed after the incident and is not mentally competent. Jessica takes the lead and insists it is merely a sick joke by him and continues with the party. Megan's young sister, Maggie, arrives, wanting to honor her sister's memory by attending the party. Later, Chugs leaves to go to her therapist appointment. Not knowing that her therapist was killed, but instead thinks he is playing a sexual game, she lies down and drinks champagne when she is suddenly murdered by a mysterious killer wearing a hooded black robe and uses the spiked tire iron. A little later, in the sorority's shower room, Claire and Jessica discussing about the incident. After they leave, a sorority girl named Joanna, who overheard their conversation, gets murdered by the mysterious killer with the same tire iron. That night, the large graduation party is thrown. Claire's boyfriend, Mickey, is attacked and murdered by the hooded killer, with Ellie witnessing it. Cassidy, Claire, Jessica and Ellie regroup and all receive a text containing the video of Megan's death and a message telling them to go to the steel mine in 20 minutes or the video will be sent to the police. The girls drive to the mine shaft, and encounter Garrett, who has cut his wrists. Thinking Garrett is the one stalking them, Jessica runs over him with her vehicle. However, they discover afterward that Garrett has been receiving the same text messages they have. Ellie suspects that Megan is the killer, believing that she did not actually die and is seeking revenge. To prove that Megan is dead, the girls lower Cassidy down the shaft to check, but instead of finding Megan's body, she finds finds a message written in blood says "Theta Pi must die". Back at the now empty sorority house, the girls receive a text from Chugs' cell phone, telling them that she is dead. Afterward, Claire is killed. Searching the house for Jessica's boyfriend, Kyle, the girls bump into Maggie and their house mother, Mrs. Crenshaw (Carrie Fisher). After discovering about the incident, Mrs. Crenshaw tells the girls to lock themselves in a bedroom and to call the police while she searches for the killer, who is in the house. Maggie is shocked and leaves the room to find Megan. After a game of cat and mouse in the kitchen, Mrs. Crenshaw is killed. The girls hear the shots from Mrs Crenshaw's shotgun and believe that she killed Megan. With no cell phones around, Cassidy and Jessica decide to find Mickey's body and use his cell, telling Ellie to run if she gets the chance. Downstairs, the killer confronts Maggie and throws a Molotov cocktail at her, setting the house on fire. Cassidy and Jessica find Mickey's body but run into Kyle, who injures Jessica after getting into a fight with her. Cassidy and Jessica flee to an under-renovation bathroom where they find Megan's decomposing corpse hanging in the shower. Kyle attacks them there and knocks out Jessica. Before he can harm Cassidy, Kyle is killed with an axe by Andy, Cassidy's boyfriend, who reveals himself to be the killer. Andy at first protected them by keeping the knowledge to himself. Since Andy wanted to have a perfect future with Cassidy, but she was always at risk of being found out. So, Andy decided to kill everyone who knew of Megan's murder. Andy then kills Jessica and tells Cassidy that they need to kill Ellie too. Cassidy is opposed to this, but Andy says that the geekish Ellie is the weakest and reveals that Ellie was the one who confided in him all about Megan's death, so she will be likely to tell someone else. Devising a plan, Cassidy plays along and tells Andy that Ellie is in the basement, and while Andy goes to look for her, Cassidy fetches Ellie from upstairs and they try to run out the front door, but are attacked by Andy, who is hurt that Cassidy would betray him. Urging Ellie to flee, Cassidy hits Andy with a lamp and tries to escape, but stops as she hears the cries for help of Maggie, who is trapped in the flames. Cassidy tries to help her out but Andy comes and tries to kill Maggie, but Cassidy stops him. The floor then crumbles underneath Cassidy, and she is left hanging over the burning basement. As Andy is about to finish her off, Ellie appears and shoots him with Mrs. Crenshaw's shotgun. He falls backward onto the burning floor, which collapses under him and he falls to his death into the flames. With Andy dead, Ellie tells Maggie to wrap a curtain around herself and run through the flames, the two then pull Cassidy back up from the hole in the floor. The three survivors, Cassidy, Ellie, and Maggie escape from the burning sorority house, just as the fire department and other emergency personnel arrive. 15 months later. Theta Pi is being renovated from the fire and Maggie is now a Theta sister. As the girls sing the Theta Pi song, a man comes into view, holding a garden trowel. The camera pans up to his wrist, revealing wrist slashing marks hinting it could be Garret who might have survived suicide/assassination attempt.

Single mother Jean (Heather Locklear) moves every time she gets her heart broken by another guy, much to the dismay of her teenage daughter, Holly (Hilary Duff). The film stats with Holly making plans to go to her first ever school dance, which is a week away, when Jean's current boyfriend comes over and reveals he has been unfaithful to Jean and then she shoves a cake into his face. After the most recent heartbreak, Jean, Holly and her little sister, Zoe, move to Brooklyn where Holly makes friends with a girl named Amy. Holly devises a plan to invent a secret admirer for her mother, so she'll be happy and stop moving. Holly overhears her friend Amy's (Vanessa Lengies) uncle Ben (Chris Noth) ordering flowers for a woman, and decides to use his advice on women (which she acquires by telling him she needs help for a English paper on romantic leads and their modern counterparts). Following Ben's advice, she sends her mother orchids and other gifts and love notes, and is soon communicating with her mother as this fictitious admirer (who Holly names Ben) via the internet. As her mother becomes more interested, Holly has to find a photo of this admirer. She sends one of the real Ben, and then devises a reason why they can't meet in person, claiming he is opening a restaurant in China. While she is developing the online romance between her mother and fake Ben, and preventing her mother and the real Ben from meeting in person, she finds herself drawn to a cute, artistic boy in her class, Adam (Ben Feldman), but is unwilling to get close to anyone due to her history of being uprooted and having to say goodbye so often. As the charade continues, and as Holly spends more time with Ben while picking his brain for romance tips, she slowly begins to see qualities in Ben which make her believe he is her mother's 'perfect man.' Unfortunately there is no way her mother can ever meet the real Ben without Holly's plan being exposed. Holly asks help from Adam to disguise as Ben in the telephone and break up with Jean. But he fails, as he is revealed to be harboring feelings for Holly too, in effect telling Holly's mother the opposite of what is planned. Next day at school, Adam admits his feelings for Holly by kissing her. That night, Lenny (Mike O'Malley), a man who is infatuated with Jean, proposes to her and she replies with a 'maybe'. Holly, as an act of desperation, then disguises herself as Ben's secretary and arranges a meeting between Ben and her mom. Next day, when Holly mistakenly believes Ben is marrying someone else, she disrupts the wedding to tell Ben he should be with her mother - not noticing he is there because the bride was his dear friend and he was catering the wedding. An angry Ben follows her out and makes her tell him the full story. Holly then goes to the meeting place and admits the whole ruse to Jean, who seems to take it badly. Days pass by and Holly and her mom maintain a cold relationship, and Holly is insulted by her interpretation of Adam's drawing of "Princess Holly." Holly begs Jean for them to move again. Her mother is humiliated and wants to stay, but Holly tells her to leave this once for Holly. She says that she always has to move for her mom. Her mom can't argue with that so they start to pack. Adam, for what he thought was the last time, went to Holly's home and gave Holly's mom his drawing, commenting that the drawing has another side, which turns out to be Adam telling Holly that he'll always be there for her. Touched, Jean logs onto the internet with Holly's screen name and talks to Adam. Adam, thinking it's Holly, says that her mom is setting a bad example, getting up and leaving when things get bad. Jean is deeply moved by this and decides to stay, finding a new job and trying to rebuild her life without running away. She also apologizes to her daughter and tells her to look at the other side of the drawing, making Holly happy. Meanwhile Ben is intrigued by what Holly told him about her mother, and with Holly's help, Jean and Ben finally meet and Jean finds her 'perfect man' at last. Holly is on the road to her perfect man as now she has some stability in her life and finally opens up and admits her feelings for Adam. At the end, Adam and Holly go to their first school dance together.
